SANTA CLARA (AP/CBS13) – The San Francisco 49ers may need to find a temporary new home after Santa Clara County on Saturday banned all contact sports from holding games and practices for the next three weeks.

County officials issued the directives in response to rising cases of the coronavirus in the area. The rules take effect Monday and will last until Dec 21.

The 49ers have home games scheduled for Dec. 7 against Buffalo and Dec. 13 against Washington at Levi’s Stadium in Santa Clara. The team also practices at that site in the county. The team had no immediate comment on the new rules.

The rules also will impact the San Jose Sharks of the NHL and college teams at Stanford and San Jose State.

“For those teams, they will not be able to play games or have practices where they have direct contact, within the county,” Santa Clara County counsel James Williams said.

Williams said he has been in touch with the teams. None immediately responded to requests for comment.

Along with banning contact sports, the new rules also require anyone who has traveled more than 150 miles from the county to quarantine for 14 days. The 49ers are playing Sunday at the Los Angeles Rams but will return from that trip before the rules go into effect at 12:01 a.m. Monday.

“This pandemic is like a high-speed train, and our projections tell us that we are on target to derail by around the third week of December,” said Santa Clara County Health Officer Dr. Sara Cody. “If we don’t apply brakes, right now with all our collective might.”

Cody said Santa Clara County has the highest case rate in the Bay Area, leading to the stricter rules. The county was reporting over 33,000 total cases and nearly 500 deaths over the course of the pandemic. The county said in a news release that the 760 new cases recorded on Friday marked the highest single-day increase for Santa Clara so far.

If the other counties don’t follow, the 49ers could look to play at the Oakland Coliseum — the Raiders’ old home — or possibly the Giants’ baseball stadium in San Francisco.

The NHL hasn’t announced a date for the start of training camp but the Sharks have said they would look into alternate sites if needed. Several Sharks players have been holding informal workouts at the team facility in small groups.

Stanford and San Jose State also have several sports in season. The Cardinals have one scheduled home football game left on Dec. 12 against Oregon State.
